PCR modification was performed by using two sets of primers specific for BLV gag gene and bovine kappa-casein gene (CASK) which show the possibility of disclosing BLV misdiagnosis. The results obtained indicate that the described PCR modification can be proposed as a simple and reliable method of BLV provirus detection.
This paper is focused on cloning and bioinformatical as well as immunological characterisation of the new vaccine antigen candidate against fasciolosis - Fasciola hepatica phosphoglycerate kinase (FhPGK). The antigen was cloned from the adult fluke by the use of RACE-PCR method. It was found that FhPGK is not a secretory and not a stage specific protein. It is present in all kinds of parasite tissue, particularly in fluke intestine and tegumental as well as subtegumental layers. FhPGK is involved in production of the first ATP molecule in the glycolytic pathway and can be used in vaccination trials in which the strategy is to block fluke's energy metabolism. This is the first, to date, phosphoglycerate kinase cloned from F. hepatica.
